我有一个使用MySQL的PHP表单并将数据传递到另一个页面,在第一页中,一个mysql查询选择一些记录然后将其打印在页面上,其中一个记录显然是ID,也是打印的在隐藏字段的值中,以便在下一页中使用它
<input type="hidden" name="cat_id" value="<?php echo $row['id']; ?>" />
并且结果是正确的,我在检查页面输出代码时有10个不同的ID
<input type="hidden" name="cat_id" value="1" />
<input type="hidden" name="cat_id" value="2" />
<input type="hidden" name="cat_id" value="3" />
...
当我提交表单时出现问题(每个数据库结果都有1个表单,所以如果我有10个条目,我还有10个隐藏字段,其中包含10个不同的值),即使我提交第二个或第10 形式,在下一页中,$ _POST ['cat_id']的值始终为1,根据$ _POST的一般打印
Array
(
[cat_id] => 1
)
有人明白为什么吗?
编辑:添加完整表单输出脚本以进行说明
<div class="container">
<div class="row">
<?php
if($c == 0){
?>

<?php
} else {
while($row = $result->fetch_assoc()) {

答案 0 :(得分:0)
您的表单已损坏,在表单关闭之前不能关闭其父元素:
<div class="modal-body">
<p>Perfavore inserisci la password necessaria per visualizzare questo elemento</p>
<form action="show.php" method="post">
<input type="password" class="form-control" name="psw" />
<input type="hidden" name="cat_id" value="<?php echo $row['id']; ?>" />
</div> <!-- HERE IS YOUR ISSUE -->
<div class="modal-footer"> <!-- HERE IS YOUR ISSUE -->
<button type="button" class="btn btn-default" data-dismiss="modal">Chiudi</button>
<button type="submit" class="btn btn-primary" name="view">Prosegui</button>
</form>
</div>
看起来应该更像这样:
<form action="show.php" method="post">
<div class="modal-body">
<p>Perfavore inserisci la password necessaria per visualizzare questo elemento</p>
<input type="password" class="form-control" name="psw" />
<input type="hidden" name="cat_id" value="<?php echo $row['id']; ?>" />
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Chiudi</button>
<button type="submit" class="btn btn-primary" name="view">Prosegui</button>
</div>
</form>
